"Tehsin delivered solid ESP32-S3 firmware for our IoT product on schedule. Code is clean and modular, with well-thought-out separation of concerns across the manager classes. He covered the full scope including captive portal provisioning, offline queue, battery monitoring, per-device auth, and reboot recovery. Documentation is thorough which makes the firmware reproducible without him. Professional communication. Recommended for IoT firmware work and would collaborate again."
